Chronic irritation and inflammation caused by inhalation of dust particles is termed pneumoconiosis. This is an occupational hazard seen mainly in people involved in the mining and stoneworking industries. Different forms of pneumoconiosis are named for the specific type of dust inhaled: silicosis (silica or quartz), anthracosis (coal dust), asbestosis (asbestos fibers).
Although the term pneumoconiosis is limited to conditions caused by inhalation of inorganic dust, lung irritation may also result from inhalation of organic dusts, such as textile or grain dusts.
